Section 5.3. Eye movement results
The same measurements of eye movements at the time of encoding
stimuli were taken for Experiments 7, 8, 9 & 10. In the individual analysis of
each of the experiments reported earlier we found that in Experiment 9 the
attention narrowing onto a negative object in a scene found in Experiments 7, 8
and 10 was eradicated. We would predict that the eye movements for
Experiment 9 will be significantly different compared to the results from the
other experiments but there would be no other significant differences between
the other experiments.
Section 5.3.1. Statistical analysis
The influence of emotion and scene component on eye movements
across different experiments was analysed by conducting a series of 3
(emotion) x 2 (scene component) x 4 (experiment) ANOVAs on the different
measures of eye movements.
Average Number of fixations
A 3 x 2 x 4 ANOVA with the repeated measures factors of emotion and
scene component and between participants factor of experiment was conducted
on the average number of fixations made. (See Figures 5.11 and 5.12). The
main effect of emotion was not significant [F(2,136) = 0.10, MSe = 0.01, p = .91,
partial eta 2 < .01]. The main effect of scene component was significant (F(1,68)
= 726.04, MSe = 967.39, p < .001, partial eta 2 = .91) with a greater number of
fixations on the object than the background. The main effect of experiment was
also significant (F(3,68) = 15.59, MSe = 19.28, p < .001, partial eta 2 = .41). The
interaction between scene component and experiment was significant (F(3,68) =
